Final Chance to Undo a 2017 Roth IRA Conversion

If you converted a traditional IRA to a Roth IRA in 2017 and your Roth IRA has sustained losses, you may want to consider whether it makes sense to undo your conversion — you have until October 15, 2018, to do so.

You also have until October 15, 2018, to convert a regular Roth IRA contribution to a traditional IRA contribution. You might wish to do so if, for example, you've determined that your 2017 income was too high, precluding you from making an annual Roth contribution in that year.
